Death by Proxy

Matt's friend Jake invites him to be an extra on one of TV's hottest crime procedurals he had the time and thought it would be a lark. Little did he know that this one day would change his life. They gave him a gun and it killed the guest star. It did not take long for the police to learn he was set up, but that did not make him feel any better. As he told Jake afterward: "I'm gonna find the son of a bitch. I just ended a life, and I don't like the feeling, and I don't like being used." Thus started a sprint to find who set him up, and it brought him in contact with come of Hollywoods' most elite as well as the nameless. "Death by Proxy" takes the reader on a search for the truth and along the way, meanders through some of Los Angeles's interesting neighborhoods and history.

Old Sins Cast Long Shadows

In this second in the series, Matt Stephens is again asked to help with a family problem. During a quiet day in the office, he's visited by a reluctant client. He wants Matt to recover some stolen art. He chose not to go to the police, as the thief might have been either his ex-wife or even his son. If so, it was a family matter. If not, he would involve the police, he just wanted to be sure before he acts. In his search for the truth, Matt discovers secret, on-line lives of the son, the ex-wife and even the client; and these secrets are causing problems. Things spiral out of control when the son is kidnapped. It takes all of Matt's skills as a PI, the assistance his computer colleague, and the help of his friend in the Russian Mafia to save the son, recover the art, and avoid getting shot.

Reviews

Review of Death by Proxy

Death by Proxy is very reminiscent of Robert B. Parker's Spencer and mysteries by Robert Crais and Michael Connelly. Matt is a solid character and the story moves along at just the right pace so you want to keep turning pages.

Review of Death by Proxy

Death by Proxy opens with one of the more inventive premises in recent crime fiction. Matt Stephens, a former insurance investigator turned occasional film extra, is handed a prop gun on a Hollywood set that unexpectedly kills the guest star. What follows is less a conventional whodunit than a compelling road novel through California, introducing an ordinary man driven by conscience into an increasingly dangerous investigation.

Review of Old Sins Cast Long Shadows

Simply Put: This novel is really good. I like the descriptions of locales that keeps the reader focused. The plot complications are nicely done and keep me, the reader, on edge! One thing that may be different than a lot of mystery novels is the technical aspect. The reader is introduced to "the dark web," and to other aspects of working on the web that many (like me!) will have not any clue about. Wow! (I have to reread some of the technical details.) I highly recommend this Matt Stephens novel authored by Ken Amster.

Read Full Biography

Ken Amster has had a varied life. It can best be described as bi-coastal, with a few years spent in the middle. He was born at Walter Reed Army Hospital in Washington, D.C., but his family moved shortly afterward to Palo Alto, California. It was a happening place in the 1960s, and at an early age he experienced the Bay Area at its finest. As a kid, he saw Fisherman’s Wharf and Golden Gate Park. His family later moved back east, where he experienced the 1970s in Washington, D.C., including the first Earth Day, Vietnam War protests, and the Nixon impeachment. College brought him to Oberlin, Ohio.

His work experience was almost exclusively in public service. He completed internships on Capitol Hill while in college, worked at the Environmental Protection Agency, consulted for the Department of Energy, and, after returning to California, built a long career as a defense analyst for the U.S. Navy at China Lake, a small town on the eastern side of the Sierra Nevada.

Outside of work, he pursued adventures throughout the United States and abroad. He bicycled along the coasts of Oregon and California, spent several years with a Sierra Nevada mountain rescue group, and canoed through the Everglades. His overseas travels included trekking in Nepal, crossing the Tibetan Plateau to Lhasa, visiting Beijing, walking part of the Great Wall, and exploring the Forbidden City. He also traveled through London, Edinburgh, Paris, Brussels, Amsterdam, and Mykonos.

He has been writing for more than ten years but began pursuing it in earnest after retiring in 2023. Since then, he has completed the first two Matt Stephens mysteries and is currently working on the third.
